We’re living in a new kind of computing environment. Everyone has a device, sometimes multiple devices. It’s been a long time since we have had this rate of change—it probably hasn’t happened since the birth of personal computing 40 years ago. To make the most of these opportunities, we need to focus—otherwise we spread ourselves too thin and lack impact. So today we’re announcing some more closures, bringing the total to 70 features or services closed since our spring cleaning began in 2011:

Apps Script will be deprecating the GUI Builder and five UiApp widgets in order to focus efforts on Html Service. The rest of the Ui Service will not be affected. The GUI Builder will continue to be available until September 16, 2013. For more information see our post on the Google Apps Developer Blog.

CalDAV APIwill become available for whitelisted developers, and will be shut down for other developers on September 16, 2013. Most developers’ use cases are handled well by Google Calendar API, which we recommend using instead. If you’re a developer and the Calendar API won’t work for you, please fill out this form to tell us about your use case and request access to whitelisted-only CalDAV API.

Google Building Maker helped people to make three-dimensional building models for Google Earth and Maps. It will be retired on June 1, but users are still able to access and export their models from the 3D Warehouse. We’ll continue to expand the availability of comprehensive and accurate new 3D imagery on Google Earth, and people can still use Google Map Maker to add building information such as outlines and heights to Google Maps.

Google Cloud Connect is a plug-in to help people work in the cloud by automatically saving Microsoft Office files from Windows PCs in Google Drive. But installing Google Drive on your desktop achieves the same thing more effectively—and Drive works not only on Windows, but also on Mac, Android and iOS devices. Existing users will no longer be able to use Cloud Connect as of April 30.

We launched Google Reader in 2005 in an effort to make it easy for people to discover and keep tabs on their favorite websites. While the product has a loyal following, over the years usage has declined. So, on July 1, 2013, we will retire Google Reader. Users and developers interested in RSS alternatives can export their data, including their subscriptions, with Google Takeout over the course of the next four months.

Beginning next week, we're ending support for the Google Voice App for Blackberry. For Blackberry users who want to continue using Google Voice, we recommend they use our HTML5 app, which is more secure and easier for us to keep up to date. Our HTML5 site is compatible with users with Blackberry version 6 and newer.

We’re deprecating our Search API for Shopping, which has enabled developers to create shopping apps based on Google’s Product Search data. While we believe in the value this offering provided, we’re shifting our focus to concentrate on creating a better shopping experience for users through Google Shopping. We’ll shut the API down completely on September 16, 2013.

Beginning today we’ll no longer sell or provide updates for Snapseed Desktop for Macintosh and Windows. Existing customers will continue to be able to download the software and can contact us for support. We’ll continue to offer the Snapseed mobile app on iOS and Android for free.

These changes are never easy. But by focusing our efforts, we can concentrate on building great products that really help in their lives.

Update March 15, 2013: We worked with the developers who provide 98 percent of our current CalDAV traffic to assure access to the CalDAV API, which means many popular products will not be impacted. We remain committed to supporting open protocols like CalDAV.
